Molecular diversity and assessment of reactions of pepper pure line germplasm to Botrytis cinerea

Abstract

The host resistance level of pure line materials was assessed in the genepool for the purpose of breeding. The highest resistance to the pathogen was observed in bell-type pepper. Moreover, genetic diversity of pure lines was investigated using selected inter-simple sequence repeat (ISSR) primers. Generally, genetic markers showed genetic diversity, so that long-type pure lines were separated from the other accessions. This is the first report on host reactions of Turkish pure lines as breeding material. These results provide significant information for future pepper breeding programs.
